Specification of Letters Patent.

Application filed January 12, 1914. Serial No. 811,512.

To all whom it may concern:

Be it known that I, GEORGE W. WILSON, a citizen of the United States, residing at Beaumont, in the county of Jefferson and State of Texas, have invented certain new and useful Improvements in Furnaces, of which the following is a specification.

This invention relates to new and useful improvements in furnaces, and has particu lar relation to such furnaces as are adapted to be used in connection with stationary boilers Where oil is employed as a fuel, but the character of furnace herein shown and described may also be adapted for use in connection with locomotive boilers.

The object of the invention is to provide a furnace of the character described which is divided into upper and lower compartments by means of a transverse partition, the upper compartment forming a combustion chamber and the transverse partition being formed of open-work so as to permit the free passage and distribution of air from the lower compartment up into the combustion chamber.

Another feature of the invention resides in the provision of means whereby the water, with which the boiler is supplied, may be circulated through the partition support for the dual purpose of keeping said support cool and preventing it from melting and also for the purpose of heating the water before it enters the boiler.

WVith the above and other objects in view, the invention has particular relation to certain novel features of construction and arrangement of parts, an example of which is given in this specification and illustrated in the accompanying drawings, wherein Figure l is a longitudinal vertical sectional view of the complete furnace. Fig. 2

7 is a transverse sectional View, taken on the line aa of Fig. 1. Fig. 3 is a vertical sectional view thereof, taken on the line b?) of Fig. 1. Fig. 4 is a front end view of the furnace. Fig. 5 is an enlarged fragmentary transverse sectional view of the furnace, showing a modified form of support for the transverse partition. Fig. 6 is an enlarged fragmentary frontend view of the furnace.

Fig. 7 is an enlarged fragmentary vertical sectional view ofthe front end of the furnace, and Fig. 8 is an enlarged fragmentary vertical sectional view of a modified form thereof.

Referring now more particularly to the drawings, wherein like numerals of reference designate similar parts in each of the figures, the numeral 1 refers to a suitable base which supports the furnace, said base being formed of concrete or any other suitable material. Upon this base the side walls 2, 2 and end walls 3, 3 are supported, said walls forming an inclosed chamber. In the upper part of this chamber the boiler 4 is mounted, said boiler being supported upon the front wall 3 and by the side walls 2, 2, but its rear end does not extend entirely back to the rear wall 3. A splash wall 5 extends entirely across the chamber from side to side and projects up a considerable di tance therein leaving a passageway between the top thereof and the boiler 4 and the space between the splash wall 5 and the rear wall 3 is usually filled with earth 6, forming a narrow flue 7 for the passage of the smoke and flame from the combustion chamber. The splash wall is usually located about two thirds of the way from the rear to the front wall 3 and the chamber in front of said splash wall is separated by a transverse partition 8 into upper and lower compartments 9 and 10, said upper compartment forming the combustion chamber. Fuel is admitted, under compression, through the line 11 and is discharged into the combustion chamber through the nozzles 12, 12, which are connected with said line, and which project through the respective orifices 13, 13 in the front wall 3. The oil is thrown against the splash wall 5 and thereby more completely atomized and in front of this wall combustion takes place. The front wall 3 is also provided with orifices 14, 14, provided for the easy observation of the interior of the furnace.

The partition 8 is preferably formed of brick spaced apart as shown more in detail in Fig. 5 and sections 15, 15 of the front wall 3, opposite the chamber 10, are formed of open brickwork, so as to permit the free passage of air into the compartment 10 and thence said air passes up through the parti tion 8 and is more evenly supplied to and distributed in the combustion chamber 9, thereby causing a more perfect combustion of the fuel. In furnaces of this character now in common use, it is common to admit both the air and fuel through the same opening, the air entering in uneven drafts and not being uniformly distributed and co-mingled with the fuel.

The brick forming the partition 8 maybe supported by means of transverse pipe sections 16, whose respective ends are secured in the walls 2, 2, as shown in Fig. 2, or the water line 17, through which water is supplied to the boiler, may be coiled, as shown in Fig. 2 and formed into a support for said partition, the ends of the coils being supported by the walls 2, 2. In case this latter form of support for the partition 8 is employed, the water passing through the line 17 to the boiler will keep the partition support 0001 and protect it against'melting and will furthermore heat 'thewater before it enters the boiler, thereby serving also the purpose of a heat economizer.

The compartment 10 may'hav'e two forms, as illustrated in Figs. 7 and 8. In Fig. 7 the bottom of said compartment has a rearward inclination and the partition8is parallel therewith, while in Fig. '8 the bottom of compartment 10 is horizontal. In the form shown in Fig 7, more air space will be provided in the compartment 10 and the supporting means of the partition 8 will consequently not become so hot, or so liable to melt as a result of the intense heat in the furnace. The form shown in Fig. 8 will be of somewhat easier construction than that shown in Fig. 7 and in case water is circulated through the partition support,'as hereinbefore explained, said support is not liable to melt by reason ofthe heat in'the furnace. The admission of air to'the compartment 10 may be easily regulated by means of the shutters 18-, 18 by means of which the'air inlets may be partially, or totally closed. The'heat formed in'the combustion chamber 9 passes along the'flue 7 and enters the rear ends of the flue pipes 19 of theboiler 4; and thence passes along said pipes to the front end of the boiler and the smoke and refuse are discharged through the smoke stack 20.

The chief feature of this furnace resides in the provision of the transverse partition 8, formed of open-work soas'to permit the free passage and distribution of air therethrough, in combination with a means for delivering fuel into the upper compartment and for admitting'air into the lower compartment. By means of this arrangement abundance of air is admitted into the combustion chamber and evenly distributed therethrough causing a complete combustion of the fuel and leaving practically no waste products,'such'as smoke and soot.

While only two forms of the furnace have been shown and described, it is apparent that the details of construction can be'varied without departing from the principle of the invention and the right to make mechanical and structural changes therein is hereby reserved, so long as such changes do not depart from the scope of the appended claims. I

What I claim is 1. A furnace consisting of a chamber, a transverse partition separating the chamber into upper and lower compartments, said partition having a plurality of air passageways therethrough, a plurality of pipe sections supporting said partition, said sections being connected together and forming a continuous fluidpassageway therethrough, a fuel inlet arranged to discharge into the upper compartment, a section of the wall of the lower compartment being formed of open brick work to permit the free passage of air therethrough, and shutters controlling the passageway ofair throughsaid open brick work. I

2. A furnace 'consistingof ajchamber, a transverse partition separating the chamber into upper and lower compartments, said partition having a plurality of air passageways therethrough,a plurality of pipe sections supportin aid partition, said sections being connected together and forming a continuous fluid passageway therethrough,

a fuel inlet arranged to discharge into the upper compartment, a splash wall arranged at the side of the chamber-opposite the fuel inlet, and a section of the wall of the lower compartment being formed of open-brick work to permit the free passage of air therethrough, and means for controlling" said air passageway.

8. A furnace consisting of a chamber, a

transverse partition formed of a'single layer of brick, spaced apart, said partition separating the chamber into upper and lower compartments anddeclining inwardly, the bottom of the lower compartment also declining inwardly and lying approximately parallel to the partition,-a'plurality of pipe sections supporting the partition, said-sectionsbeing connected together and forming a continuous fluid passageway therethrough, a fuel inlet arranged to discharge into the upper compartment, a sectionofthe'wall of the lower compartment being formed of' open brick work to permit the free passage of air therethrough, and means for-controlling the passage of air through the open brick work.
